Usually dilations have a center of dilation at the origin (0,0). When this occurs all we need to do is multiply each coordinate by the dilation scale. Unfortunately things get a little more complicated when the center of dilation is not at the origin.
In this case the center of dilation is located at F: (3,1)
The first step we must take is to find how many units point F is from vertex A.
In this case, F is 4 unit up and 8 units right of vertex A. (Reference the first image below to see how I found this)
Now we must multiply these dimensions (4 units and 8 units) by the factor of dilation (0.25)
4 * 0.25 = 1
8 * 0.25 = 2
This shows us how many dimensions away point [tex]A^{1}[/tex] is from point F:
1 unit vertically
2 units horizontally
Now how do we know if [tex]A^{1}[/tex] is above or below, left or right from point F? Easy! There has been no translations so the directions will be the same as the original:
Point F: (3, 1) ---> (3-2, 1-1) ---> (1, 0)
Reference the second image to see this
Hopefully this helps and makes sense. Let me know if you need further explanation or clarification.

Ida needs to hire a singer for her wedding. Singer A is offering his services for an initial $80 in addition to $13.35 per hour. Singer B is offering her services for an initial $86 in addition to 11.65 per hour. When will the two singers charge the same amount for money?
Answers
Answer:
The two singers will charge the same amount for money at 3.53 hours
Step-by-step explanation:
Let the number of hours be represented by y
Ida needs to hire a singer for her wedding.
Singer A is offering his services for an initial $80 in addition to $13.35 per hour.
= $80 + $13.35(y)
= 80 + 13.35y
Singer B is offering her services for an initial $86 in addition to 11.65 per hour.
= $86 + $11.65 × y
= 86+ 11.65y
When will the two singers charge the same amount for money?
Singer A = Singer B
80 + 13.35y = 86+ 11.65y
Collect like terms
= 13.35y - 11.65y = 86 - 80
1.7y = 6
y = 6/1.7
y = 3.5294117647 hours
Approximately = 3.53 hours
The two singers will charge the same amount for money at 3.53 hours

Chang rented a truck for one day. There was a base fee of 15.95, and there was an additional charge of 88 cents for each mile driven. Chang had to pay 210.43 when he returned the truck. For how many miles did he drive the truck?
Answers
Answer:
221 Miles
Step-by-step explanation:
Since there is a base fee, you substract that from the total.
210.43 - 15.95 = 194.48.
And since it was .88 per mile, you just divide 194.48 by .88 to get 221

PART B:Round your answer to the nearest whole number. The manager's prediction is
Options: equal to, less than, greater than
the actual number of hours that Carlos and Jacob need to work to earn the same amount of money.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the expression :
Jacob's yearly income :
2000x + 3000 ; x = number of hours worked per week.
Carlos income :
3800x - 40000
Managers prediction = 35
Jacob.: 2000(35) + 3000 = 73000
Carlos : 3800(35) - 40000 = 93000
Carlos will earn more than Jacob given the manager's prediction.
Number of hours required so they can earn the same amount :
2000x + 3000 = 3800x - 40000
3000 + 40000 = 3800x - 2000x
43000 = 1800x
x = 43000/1800
x = 23.88
x = 24 hours

Please help, this is my first time! Here is the question: Maria earned a total of $504 the last two days. She worked 8 hours the first day, 4 hours the second day. How much did Maria earn every hour? Please show how you did it, this is my first time, so please help.
Answers
Answer:
$42 per hour
Step-by-step explanation:
Well,
She got $504 in total
8 + 4 = 12 (the total number of hours worked)
To find out how much she earned per hour you'll need to divide.
$504 ÷ 12
which equals $42
Answer:
Maria earned $42 per hour.
Step-by-step explanation:
First, we need to add the total amount of hours she worked.
8 + 4 = 12
Next, we need to divide 504 and 12 to see how much she earned per hour.
504 ÷ 12 = 42.
So, Maria earned $42 per hour.

Nadia charges $5.50 an hour for babysitting. She babysits 17.50 hours the first week of the month and 21 hours the second week of the month.
Suppose Nadia raises her rate by $0.55 an hour. How many hours would she need to work to earn the same amount of money she made in the first two weeks of the month?
Answers
Answer:
about 34 hours
Step-by-step explanation:
Answer:
35 hours.
Step-by-step explanation:
To achieve an answer to this question, we'll have to set two expressions equal to each other.
Let's first start by calculating how much Nadia has made in the first two weeks of the month. We can do this by adding the amount of hours she works in the first and second week together:
[tex]21+17.5[/tex]
[tex]=38.5[/tex]
Let [tex]h[/tex] equal hours.
Set up your first expression:
[tex]5.50h[/tex]
Let's go ahead and substitute 38.5 into the expression to see how much money she will make the first two weeks of the month at a rate of $5.50 an hour:
[tex]5.50(38.5)[/tex]
[tex]=211.75[/tex]
We are told that Nadia raises her rate by $0.55, so we'll need to add 0.55 to 5.50 in order to find her increased rate:
[tex]5.50+0.55[/tex]
[tex]=6.05[/tex]
Set up your second expression:
[tex]6.05h[/tex]
Now, set this equal to how much she made the first two weeks at a rate of $5.50 an hour:
[tex]211.75=6.05h[/tex]
Divide both sides of the equation by the coefficient of [tex]h[/tex], which is [tex]6.05[/tex]:
[tex]35=h[/tex]
Therefore, it will take Nadia 35 hours to earn the same amount of money she made in the first two weeks of the month.
_
Check your work by substituting 35 for [tex]h[/tex] in the equation below:
[tex]211.75=6.05h[/tex]
[tex]211.75=6.05(35)[/tex]
[tex]211.75=211.75[/tex]
Since both sides of the equation are equal to each other, our answer is correct!

Rewrite the whole as a fraction using 5 as the denominator: 6= 6/1=6×5/5
Equivalent fraction: the fraction thus generated looks different but has the same value as everything.
2.2 sum of the two equivalent fractions add two equivalent fractions that now have a common denominator

A different store needs to make at least $20,000 to make a profit in March. They average $685 a day for the month. James used rounding and estimation to say, "$685 is almost $700. $700 × 30 days is $21,000. I think it is going to be a close call!" What do you think?

Since they average $685 a day for the month. This means for the month, they'll make:

Approximating $20,550 will give $21000 and since James used rounding and estimation to say, "$685 is almost $700 and $700 × 30 days is $21,000. James is quite correct.

The soccer team is conducting a fundraiser selling long-sleeved T-shirts for $14 and short-sleeved T-shirts for $10. So far the team has sold less than $200 worth of the two types of T-shirts.

x + y 200
14x + 10y > 200
14x + 10y < 200
Answers
Answer:
14x +10y < 200
Step-by-step explanation:
The inequality that represents the given condition is: 14x + 10 y < 200.
What is an inequality?"An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions."
Given, the price per long sleeved t-shirt is $14.
The price per short sleeved t-shirt is $10.
The soccer team has sold less than $200 worth of both types of t-shirts.
Here, the number of long-sleeved t-shirts they have sold is 'x'.
The number of short-sleeved t-shirts they have sold is 'y'.
Therefore, the total price of long sleeved t-shirt sold is = $14 × x = $14x
The total price of short sleeved t-shirt sold is = $10 × y = $10y
Therefore, the required inequality will be:
14x + 10 y < 200

Graphic Representation of the Equations :
3y + 2x = 1 -6y + 4x = -2
Solve by Substitution :
Solve equation [2] for the variable x
[2] 4x = 6y - 2
[2] x = 3y/2 - 1/2
Plug this in for variable x in equation [1]
[1] 2•(3y/2-1/2) + 3y = 1
[1] 6y = 2
Solve equation [1] for the variable y
[1] 6y = 2
[1] y = 1/3
